AP Provides Scheduling Flexibility
Pursuing the IB diploma requires taking 6 classes.
Students who go the AP route can choose to take as many AP classes as they wish. They can also pursue non-AP classes such as dual credits, "honors," or extra curriculars
AP Students don't have to take a language or art credit. However, if they want to, they can pursue many whereas IB Students can only pursue one

It might be viewed as more legitimate
